raise NotImplemented for series(f(x))
raise NotImplemented for series(f(x))

    Until issue 1620 is addressed, there is no way to represent the
    series of a generic function like f(x) so an error is now raised.

    Note f(x) and cos(x) are both functions; the difference is that
    f does not have any arguments (though f(x) has 1) and f does
    not have an inverse:

    >>> f = Function('f')
    >>> f.nargs
    >>> hasattr(f, 'inverse')
    False
